Readable Text - The font and font size make reading numbers very hard on consumables so much that it actually begins to recede into the corner of the hotbar slot that its in. Make the text smaller yet readable. Might even make the background of item boxes black or something.

Size of the UI itself - Make the size of the UI a tad bit smaller, it seems oversized and blocky.

Number of Bag Slots Left - Please put some sort of notification telling the player how many open slots he has left.

Recharge Time Left - Place a timer on moves/consumables telling us how much time we have left until it is off cooldown.
